Soylu did not specify which PKK bases the planned operation would target but President Recep Tayyip Erdoğan has previously said it would be against militant hideouts in Iraq.
Soylu also said there are now less than 700 militants in Turkey as the country takes significant measures on its borders to block militant entries.
“There are less than 700 terrorists in Turkey. The terrorist entry into the country is so little, as well. 12 people entered Turkey since January. We are taking serious measures at our borders,” Soylu said.
